BONE-CUTTINGMACHINE.

SPECIFICATION formingpart of Letters Patent No. 744,647, dated November 17, 1903.

Application filed Angust 31, 1901. Serial No. 73,941. tllo modeLl To all whom it may concern: Be it known that I, CHRISTOPHER TRICK, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and useful Improvementsin Bone-Cutting Machines; and I do declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.

My invention relates to bone-cutting machines whereby green bones and analogous articles are reduced for-chicken and other animal food, and it more particularly relates to improvements in my Letters Patent No. 610,335, granted September 6, 1898, the improvements being in the construction of the grinding-cylinder and its shaft andin the feedingmechanism.

In the drawingsillustrating my invention, Figure 1 is a side elevation view of a machine embodying myimprovements, the hand driving-wheel being removed. Fig. 2 is a plan view thereof, some of the parts being broken away on line X X of Fig. 1. Fig. 3 is a sectional elevation view on line X X of Fig. 2, and Fig. 4 is an enlarged view of the grinding-cylinder broken away to its longitudinal center.

In said drawings the parts similar to those shown in my aforesaid Letters Patent are designated by the same numerals therein employed, while theimproved parts are desthe edges of cylinder A, thereby admitting the hands or tools into the hollow of cylinder-A for repairs, &c., as well as to facilitate the discharge of the ground food from the opposite ends of cylinder A that is admitted thereto through the openings in cylinder A through which therknives 6 and 7 project.

The bore of said cylinder A is of a common diameter on both sides of the central dividing-wall E thereof and tapering outward therefrom and increasing toward the ends of G,' engaging ratchet wheel H, secured to shaft I, provided with suitable bearings in a projection of the frame, wheel H being engaged by retaining-pawl J ,also mounted upon said projection of the frame. Shaft I has socured thereto a gear-wheel K, adapted to be engaged by a rack or internally-toothed segment L, pivotally or otherwise secured to the end of arm 18 and adapted to be engaged bya flanged wheel or projection M, mounted upon said projection of the frame. The teeth on rack L are so arranged that when the hopper 14 is empty the gear K will not engage more teeth on said rack L. (See Fig. 3.) The gear, K is revolved by the reciprocation of pawl G on wheel H, caused by eccentric F.

The member M is preferably a wheel to reduce friction, and in order to unmesh and remesh rack L and gear Kat different points said wheel M is adjustably mounted on the frame, in the instance shown by being mounted on a member N, having shank n slidingly mounted in a yoke O, removably secured to the frame by bolts 0, and a springP holds wheel M against rack'L and maintains the relative engaging positions of rack L and gear K. j

Shafts B B have on opposite ends wheels R and S, respectively, for power and hand driving, Wheel S having handle T for handdriving.

The combination of aframe, a cutting-cylinder provided with trunnions and means for connected with the free end of the arm, a from one of the cylinder trunnions and 10 shaft mounted on the frame, a pinion carried thereby rotate the ratchet-wheel and pinion. thereby engaging said rack, and with which In testimony whereof I afiix my' signature the plain part of the bar comes in contact in the presence of two Witnesses.

when the plun er reaches the bottom of the hopper, a ratcITet-wheel carried by the pinu TRICK ion-shaft, a pawl engaging said ratchet- Witnesses:

wheel, and a second pawl engaging said W. W. DUNKIN,

ratchet-wheel, and means to reciprocate it J. A. ULRICH.
